Topological Phase Transitions in the Golden String-Net Model
M. D. Schulz, S. Dusuel, K. P. Schmidt +1
We examine the zero-temperature phase diagram of the two-dimensional Levin-Wen string-net model with Fibonacci anyons in the presence of competing interactions. Combining high-orde…
Breakdown of a perturbed Z_N topological phase
M. D. Schulz, S. Dusuel, R. Orus +2
We study the robustness of a generalized Kitaev's toric code with Z_N degrees of freedom in the presence of local perturbations. For N=2, this model reduces to the conventional tor…
Quantum phase transitions in fully connected spin models: an entanglement perspective
M. Filippone, S. Dusuel, J. Vidal
We consider a set of fully connected spins models that display first- or second-order transitions and for which we compute the ground-state entanglement in the thermodynamical limi…
Robustness of a perturbed topological phase
S. Dusuel, M. Kamfor, R. Orus +2
We investigate the stability of the topological phase of the toric code model in the presence of a uniform magnetic field by means of variational and high-order series expansion ap…
Universality of the negativity in the Lipkin-Meshkov-Glick model
H. Wichterich, J. Vidal, S. Bose
The entanglement between noncomplementary blocks of a many-body system, where a part of the system forms an ignored environment, is a largely untouched problem without analytic res…
Exact spectrum of the Lipkin-Meshkov-Glick model in the thermodynamic limit and finite-size corrections
P. Ribeiro, J. Vidal, R. Mosseri
The spectrum of the Lipkin-Meshkov-Glick model is exactly derived in the thermodynamic limit by means of a spin coherent states formalism. In the first step, a classical analysis a…
